Defender Relay sends transactions via HTTP API, automating smart contract operations securely.
OpenZeppelin created its Defender Relay service to allow users to send transactions via a regular HTTP API. Defender Relay provides a gasless meta-transaction relay that ensures a seamless and cost-efficient experience. For developers, there is no need to monitor transactions or use a backend script to secure private keys because the protocol takes care of everything from resubmissions to private key secure storage to the signing of transactions.
